<jats:sec id="abs1-1"><jats:title>Background</jats:title><jats:p>Family Nurse Partnership (FNP) is a home-based nurse home-visiting programme to support vulnerable parents. Group Family Nurse Partnership (gFNP) has similar aims and materials and was demonstrated to be feasible in implementation evaluations.</jats:p></jats:sec><jats:sec id="abs1-2"><jats:title>Objectives</jats:title><jats:p>To determine whether or not gFNP, compared with usual care, could reduce risk factors for maltreatment in a vulnerable group and be cost-effective.</jats:p></jats:sec><jats:sec id="abs1-3"><jats:title>Design</jats:title><jats:p>A multisite randomised controlled parallel-group trial and prospective economic evaluation, with eligible women allocated (minimised by site and maternal age group) to gFNP or usual care.</jats:p></jats:sec><jats:sec id="abs1-4"><jats:title>Setting</jats:title><jats:p>Community locations in the UK.</jats:p></jats:sec><jats:sec id="abs1-5"><jats:title>Participants</jats:title><jats:p>Expectant mothers aged &lt; 20 years with one or more previous live births, or expectant mothers aged 20–24 years with no previous live births and with low educational qualifications (defined as General Certificate of Education at grade C or higher in neither mathematics nor English language or, if they had both, no more than four General Certificates of Education at grade C or higher).</jats:p></jats:sec><jats:sec id="abs1-6"><jats:title>Intervention</jats:title><jats:p>Forty-four sessions of gFNP (14 during pregnancy and 30 in the first 12 months after birth) were offered to groups of between 8 and 12 women with similar expected delivery dates (the difference between the earliest and latest expected delivery date ranged from 8 to 10 weeks depending on the group) by two family nurses (FNs), one of whom had notified her intention to practise as a midwife.</jats:p></jats:sec><jats:sec id="abs1-7"><jats:title>Main outcome measures</jats:title><jats:p>Parenting was assessed by a self-report measure of parenting opinions, the Adult Adolescent Parenting Inventory Version 2 (AAPI-2), and an objective measure of maternal sensitivity, the CARE-Index. Cost-effectiveness was primarily expressed in terms of incremental cost per quality-adjusted life-year (QALY) gained.</jats:p></jats:sec><jats:sec id="abs1-8"><jats:title>Data sources</jats:title><jats:p>Interviews with participants at baseline and when infants were aged 2, 6 and 12 months. Cost information from nurse weekly logs and other service delivery data.</jats:p></jats:sec><jats:sec id="abs1-9"><jats:title>Results</jats:title><jats:p>In total, 166 women were enrolled (99 to the intervention group and 67 to the control group). Adjusting for site and maternal age group, the intention-to-treat analysis found no effect of gFNP on either of the primary outcomes. AAPI-2 total was 7.5/10 [standard error (SE) 0.1] in both arms [difference also adjusted for baseline 0.08, 95% confidence interval (CI) –0.15 to 0.28;<jats:italic>p</jats:italic> = 0.50]. CARE-Index maternal sensitivity mean: intervention 4.0 (SE 0.3); control 4.7 (SE 0.4) (difference –0.76, 95% CI –1.67 to 0.13;<jats:italic>p</jats:italic> = 0.21). The sensitivity analyses supported the primary analyses. The probability that the gFNP intervention was cost-effective based on the QALY measure did not exceed 3%. However, in terms of<jats:italic>change</jats:italic>in AAPI-2 score (baseline to 12 months), the probability that gFNP was cost-effective reached 25.1%. A separate discrete choice experiment highlighted the value placed by both pregnant women and members of the general population on non-health outcomes that were not included in the QALY metric.</jats:p></jats:sec><jats:sec id="abs1-10"><jats:title>Limitations</jats:title><jats:p>Slow recruitment resulted in smaller than ideal group sizes. In some cases, few or no sessions took place owing to low initial group size, and small groups may have contributed to attrition from the intervention. Exposure to gFNP sessions was below maximum for most group members, with only 58 of the 97 intervention participants receiving any sessions; FNs were experienced with FNP but were mainly new to delivering gFNP.</jats:p></jats:sec><jats:sec id="abs1-11"><jats:title>Conclusions</jats:title><jats:p>The trial does not support the delivery of gFNP as a means of reducing the risk of child abuse or neglect in this population.</jats:p></jats:sec><jats:sec id="abs1-12"><jats:title>Future work</jats:title><jats:p>A randomised controlled trial with modified eligibility to enable first-time mothers aged &lt; 20 years to be included, and a modified recruitment strategy to enable faster identification of potential participants from antenatal medical records.</jats:p></jats:sec><jats:sec id="abs1-13"><jats:title>Trial registration</jats:title><jats:p>Current Controlled Trials ISRCTN78814904.</jats:p></jats:sec><jats:sec id="abs1-14"><jats:title>Funding</jats:title><jats:p>This project was funded by the National Institute for Health Research (NIHR) Public Health Research programme and will be published in full in<jats:italic>Public Health Research</jats:italic>; Vol. 5, No. 9.
